Duplex models can portray complex systems with the utmost of simplicity, clarity and efficacy. The mettle of the binomial approach shows up, for instance, in debunking the welter of myths and misconceptions that pervades the fields of finance and economics.

For starters, the inquest draws only on a minute fraction of the trove of information available at the most popular portal among the investing public. Moreover, the quantitative analysis relies solely on the simplest technique in statistical testing. From a computational stance, the attendant program invokes a skimpy subset of the built-in functions within the core module of the R system: the leading choice of programming language and software platform for data science in disparate domains.
